Patients will be randomized to the chlorhexidine or no additional intervention groups. Patients will be randomized to use 4% chlorhexidine cloths, while the other half receive no additional intervention. Those randomized into the chlorhexidine gluconate home-application group will be asked to shower the night before surgery, and to use a standardized pre-packaged chlorhexidine gluconate wipe (that the patients would receive at their pre-surgical consultation) on their surgical site after thoroughly drying those areas. The patients will be asked to use a second wipe in each area the morning of surgery. The surgical sites will be analyzed in two groups: anterior cervical and posterior spine. Each of these two groups will be randomized separately. All patients will undergo a standardized preoperative cleansing regimen. Once positioned, they will be cleansed with an alcohol solution. Then, the surgical site (either the anterior portion of the neck or the posterior area of the spine) will be scrubbed with chlorhexidine soaked brushes and then painted with chlorhexidine solution. Perioperative antibiotics will be given per attending surgeon preference. Cutaneous samples will be taken from the surgical site of each patient at each time point.
